Copiamycin, an antibiotic agent, has shown in vitro activity against Candida albicans, Torulopsis glabrata, and Trichomonas vaginalis. Local administration of copiamycin to mice inoculated intraperitoneally with protozoa reduced the per cent of infection as measured by decreased abscess formation. This antibiotic has had little effect on the glucose oxidation by protozoa. Its action on anaerobi...

this study examined sourdough lab containing specific starter cultures used to produce barbari-style bread and evaluated their microbiological shelf life and sensory properties. the effects of sourdough fermentation time (8, 16, 24h), fermentation temperature (28, 32, 36°c) and type of starter culture (lactobacillus sanfransicencis, atcc 14917; lactobacillus plantarum, atcc 43332; a mixture of ...

background: this study aimed to investigate and compare the bacterial safety of handmade and commercial ready‑to‑use enteral feeding formulas used in an iranian teaching hospital. methods: in this experimental study, a total number of 70 samples (21 handmade formulas sampled at two sampling times, i.e. the time of preparation and 18 h after preparation, and 28 commercial ready‑to‑use formulas) ...

The most exciting advances in biohydrometallurgy are occurring in the field of microbiology. The two main technologies employed in biohydrometallurgy, agitated tanks for the processing of refractory concentrates and heaps and dumps for the processing of low-grade ores, are technologically sound and widely practised at commercial scale, but their development began at a time when very little was ...

Significant advances in water treatment over the last century have resulted in massive improvements in the microbiological safety of public drinking water supplies in the UK and the developed countries. Incidences of illness due to poor treatment or post-treatment contamination are rare, but when they occur tend to attract considerable media attention. A well managed water treatment works and s...

The present study was conducted to isolate and identify the major causing bacteria from mastitis milk sample collected from Kerala veterinaryUniversity Livestock Farm, Mannuthy. A total of fifty milk samples were collected from mastitis affected animals and microbiological testing of raw milk was done. Upon microbiological testing the major causing bacteria Staphylococcus aureusand Escherichia ...

Micrococcus luteus was employed for the assay of rifampicin in fixed-dose combinations (FDCs) of anti-tubercular drugs containing rifampicin, isoniazid, pyrazinamide and ethambutal. The microbiological assay was compared with spectrophotometric assay for estimation of rifampicin in the FDCs as well as in dissolution studies of the FDCs. The microbiological method was found to be more sensitive ...

Based on numerical simulations of gas-rich galaxy mergers, we discuss a model in which quasar activity is tied to the self-regulated growth of supermassive black holes in galaxies. The nuclear inflow of gas attending a galaxy collision triggers a starburst and feeds black hole growth, but for most of the duration of the starburst, the black hole is “buried”, being heavily obscured by surroundin...
